Specication of Letters Patent No. 22,756, dated January 25, 1859.

Be it known that I, WM. B. TWIFORD, of Chincoteague, in the county of Accomac and State of Virginia, have invented a new and useful Improvement in Washing-Machines; and I do hereby declare that the following is a full, clear, and exact description of the side 1n opposite directions as shown at e, e. same, reference being had to the accompany- These inclined surfaces come in conact with ing drawings, forming a part of this specitith ledges C, and consequently cation, in which- Figure l, is a plan or top view of a Washing machine having my improvements attached. Fig. 2, is a side View of the same. Fig. 3, is a vertical longitudinal section of the same.

Similar letters of reference, in each of the several figures indicate corresponding parts.

The nature of my invention consists 1n the opposing incline planes on the underside of the ends of the sliding roller frame, in combination with fixed concave projections or ledges on the sides of the tub or box, and with grooves of greater Width than the diameter of the journals of the roller in the sides of the bax; whereby, when the roller is moved back and forth it is caused to nearly touch the bottom of the box or tub, when it arrives at the center thereof, and to rise considerably above the bottom of the same, when it arrives at either end of the tub. By having the roller operate thus, the clothes are subjected to the greatest squeezing action when the roller is at the center of the tub and allowed to li hten up, and admit a fresh crioulation og Water and air through them, when the roller is at either end of the tub, and thus an alternate squeezing and lightening up operation is being carried on,

The ends of the side pieces of frame are made inclined on their underpositions shown in red and blue lines in said figure. It is by this change in the position of the roller that the clothes are squeezed at the center of the tub and tightened up at the ends of the same, as stated in the forepart of the specification.

dlameter of the roller, and said changes beand the roller, the roller tub is supplied with water &c. clothes placed under the lowered from the position shown 1n Fig. 3, to the position shown in Fig. 2. The operators lay hold of the ends of the frame and slide it back and forth. As it thus moves, the roller partly revolves, and owing to this and the oblique position of the lower flutes, a very perfect rubbing action is obtained and the clothes washed with almost as little injury and as perfectly as b hand. IVhat I claim as my invention anv desire to secure by Letters Patent, is`

he opposing incline planes c. e, on the underside of the ends of the sliding roller frame E in combination with fixed concave projections or ledges C. C. an the sides of the tub or box, and with grooves B, of greater width than the diameter of the journals of the roller, in the sides of the box, substantially as and for the purposes set forth.

as the roller is drawn back and forth, and the clothes consequently effectually washed.

To enable others, skilled in the art, to make and use my invention, I will proceed to describe its construction and operation.

A, represents the tub or box, it has a wide horizontal slot B, in each side. The top of this slot communicates at its center with a vertical slot a, which is enlarged at its upper f termination so as to form an upper'bearing b. On the outer sides of the box are concave ledges C, C, Which serve the office of preventing the escape of water through the oblonge slots B. They also serve as guides and supports for the roller frame and IVitnesses: as lifters or elevators of the same, as will be JAMES D. CoRBIN, described. c, c, are diagonal flutes or I JOSHUA J.

grooves on the bottom of the tub.
